The ventilator has a housing (22) with side walls, and a recess including a flange in its axially extending middle area. The recess has a hollow section (36) on its axially extending part, where the section prevents the rotation of a noncircular screw head or noncircular nut relative to the recess. The hollow section has a wide section to hold the screw head in the hollow section or the nut in the wide section by a clamp connection.
